When you do it per the book you end up with a ratty looking firewall with bulges and depressions. I didn't have the foresight to do what you are thinking of with phenolic pads under the SS but other builders have done it and it greatly improves the appearance of the firewall. Don't forget to cut clearance holes in the insulation so the SS goes directly to the pads. Also, I suspect that a further advantage of the phenolic mounting pads is that your engine will sag less as you put some flight time on your plane. My spinner came down at least a quarter of an inch (relative to the cowling) in the first 50 hours. Bob Jude N65BJ
